My `invention relates to barrel-bungs, `and more particularly to thattype in which provision is made tor the escape ot `gases gen-r eratedWithin the barrel.

@ne ot the objects oft my invention isthe provisionl of a bung otthetype mentioned, which ile-"simple in construction, Vlight in Weightandreliable in action, and which Will guard against the admission ot"airinto the 1 barrel, yet Aallow the escape oi gases gener-v atedWithin thebarrels.

Another object is, to provide a bung particularly adapted for use duringthe 'termentation period of the liquid Within 4a vbarrel and whichissoconstructed that scum rising tothe surface ot the Vliquid andeventually forced out through thebung, Will have a :tree escape`andvvill not clog the passages in the bung to prevent the eseape oilgenerated Gases. *e

A still vfurther `object is, the yprovision ot an improvedbung whichvvillassure a tight sealing ot the barrel when the pressure Within isless or even a trifle more than the atmospheric pressure, and whereintheescape ot the gases and undesirable `light matter can be controlledby an element relatively adjustable .with respect tothe body ot thebung. y

Withthe above and other objects to appear hereinafter, the inventionconsists in the novel features ot' construction, and yin `thearrangementand combination` of parts `Vto `be hereinafter' described,land more partieularly pointed out inthe subjoined claims.l

Eig. ,t is a central longitudinal ysection V throughthe body `portionotlthebung, taken on line l- 4l,.ll`-ig. 3, looking in the direction ofthe arrow crossing said line.

Referring now to the drawings in detail, the reference numeral 5designates the body ot thel bung, which is longitudinally tapered intheconventionallmanner so that it may be driveninto the usualinvvarClly-jtaperedbung` hole oa barrel. rlhis body portion may beconstructed ot Wood ot suitablekindor it `desired inet-al or other matrial may be used. it has an axial bore 6, provided With a large Riloutwardly-flaringportion 7 at its outer end, serving as a valve seat,and a smaller in"- wardly-laring portion 8 fat its inner end, thecylindrical intermediate portion 9, Whioh connects `said Haringportions, being ot' a predetermined diameter so as `to properlyco-operate with another part ot the device, to `be presently described.The` inner endv faceof said body portion is provided with `radiatinggrooves or passages vl() which extend from the flaring portion 8 attlieinner end of the ibore 6 to the peripheral face of the body portionofthe bung.

A elosure ll for the bore of the body pjortion .is provided which is inthe form ot :pressurerelief-device havingV a valve 12, a valve stem i3,and a Vgrip member le the torni ot a stem orstud extending outward`axially from the valve.` The valve iscOnieal and conforms in shape andsize to the inner portion of the outwardly-flaring outer end ofthe boreor valve seat 7, against which ,it is Vfirmly seated by gravity. Thevalve, when seated,`istherei`ore in, a receding positiony and could notbe taken lioldot, 'were it not tor thelgrip member or stud 14textendingoutward axially therefrom. p l

The valve stein 13 spreterably eylindricalv and extends tl'irough thecylindrical: portion 9 ofthe bore@ and tl'irough theinvva'rdlylaring'inner end Sxot'said bore, and extends a distancebeyondthe `inner,end of the body portion ot the bung so that when thebung is driven into the bung-hole ofya barrel, stem ivill extend intothebarrel. The valve4 stem 131s of smaller diameter than the cylindricalportionl.) of the bore in the body portion of the bung,` andconsequentlyan annular passage 15 is provided around said stem, vconnecting `theinner and outer Haring `portions of the bore.

The valve stem 13 is threaded along its inner portion and has a battlemember 16 threaded thereon so that it may be adjusted and maintained inany desired spaced rela tion to the inner end ot the body portion 5.`This baiile member ispreierably tlat and circular in formation and iscomparatively ,large in diameter,*although it maybe otherwise toi-med,and 1t also serves as astop to limit the outward or unseating movementoit the valve l2. A nut 171s also threaded onto the stern ofthe valveand bears against the inner tace of said baille and/or stop member, andby reason of the latter being threaded onto the valve stem, said nutserves in the'- capacity of a` jamb-nut and guards against turning ofthe baille member on said stem.

When the bung is driven into a barrel, the

valve l2 will keep the barrel sealed as eil'ectively as though anordinary one-piece im` perforate bung Were used, and as barrels areinvariably placed in cellais and the like, the foul or musty odorscommon to sui-h places are prevented from entering the barrel antcontaminating the contents thereof. J

As it is desirable to allovr the escape of gases generated in thebarrel, also the scuin rising to the surface of the liquid duringfermentation, a relief-device, such as provided in the body portion ofmy improved bung, or the bung propei, will assure a clear, palatablebeverage without foreign taste.

When gas is generated in the barrel and rises above atmosphericpressure, plus the weight of the relief-device provided, .the

valve l2 will become unseated and the gases, and the scum, ifl any hasrisen to the surface of the liquid, will pass around the edge or edgesof the baille member 1li and pass -out through the bore Genf the bung.The extent of outward movement of the reliefdevice` Will be inaccordance with the ex cess pressure inthe barrel, butin no case greaterthan allowed by the baille or stop member 16 when the latter comes incontact with the inner end of the body portion of the bung. It Will beapparent, however, that when said baille orstop memberis in Contactwiththe inner end of the body portion of the bung, the gases have freeescape through the radiating grooves or passages l0 formed in the innerend face of saidlbody portion, as free access is provided to the outerends of these grooves or passages, especially since the baille or stopmember 16, being of smaller diameter than said body portion, leaves theouter ends of said grooves vor passages uncovered. i s e Should the scumrising through the bung adhere to parts thereof and cause the movableparts to stick, or even tend to act as a restraint against the freeaction of the movable part, it will simply be necessary to grasp thegrip memberor stud la and lift the valve l2; gas is not desired at themoment, the valve may simply be rotated, when the adhering parts willbecome loosened. e

By flaring the inner end of the bore G inwardly, the gases and scum havefree access to the annular passage l5 around the valve stein and Whenthe valve is raised, may escape freely into atmospheric air.
